find the distance between e and f on the number line below.

find the distance between e and f on the number line below.
Answer
Explanation:
Step1: Identify the coordinates
The coordinate of point $E$ is $- 10$, and the coordinate of point $F$ is $-3$.
Step2: Use the distance formula
The distance $d$ between two points $x_1$ and $x_2$ on a number - line is $d=\vert x_2 - x_1\vert$. Here, let $x_1=-10$ and $x_2 = - 3$. Then $d=\vert-3-(-10)\vert$.
Step3: Simplify the expression
$\vert-3 - (-10)\vert=\vert-3 + 10\vert=\vert7\vert = 7$.
Answer:
$7$
